User Review: Outdoor Research Alpine Bivy
Design: single pole bivy
Ease of Setup: very easy
Weight: >2 pounds
Price Paid: $199
This bivy is made of a 3-layer GORE-TEX fabric, which is EXTREMELY waterproof, windproof, and overall weatherproof. I have put a hose at high power right against the fabric, and it has never bled threw. The only reason why I gave this bivy 3 stars is that I wanted to do long-distance ultralight backpacking. This is not good for backpacking!! It's heaver then a lot of bivies, and it's pretty much the same as all bivies in 3-season use.
I recommend this to any climbers and mountaineers. I lent this to my friend who went to climb Mount Ranier. He said it was good for snowy conditions, and he expected it would work in snow caves very well. If you are a mountaineer, or maybe a canoe camper, this would be a 5-star piece of gear for you.
